' To all whom it may concern panying drawings.

My invention relates tothat class of hand levers that are provided with means for retaining it in difierent predetermined positions, and is especially directed to mechanism whereby the retaining means is actuated to release said lever, and is particularly applicable to cultivators and similar implements.

The principal objects of my invention are to provide a hand lever with means for looking it in different predetermined positions, which is simple in construction, having a minimum number of operative parts; to provide locking means so constructed and arranged as to be self engaging; and to provide means that may be easily actuated to release said lever.

Specifically stated the form of my invention hereinafter described comprehends a pivoted hand-grip having a spring leaf or blade forming a link connected with a detent which is arranged to be shifted longitudinally by flexing said leaf or blade out of its normal alinement.

My invention also includes all of the various novel features of construction and argaigement hereinafter more definitely speci- In the accompanying drawings, Figure l is a side elevational view of a hand lever embodying a convenientform of my invention; Fig. 2 is a front elevational view of the hand lever shown in Fig. 1 as viewed from the right side of said figure; Fig. 3 is a side elevational view of a different form of lever showing my invention adapted thereto; and Fig. 4 is a front elevational view of the structure shown in Fig. 3.

In said figures the hand lever 1 having the handle 2 is fulcrumed to rock upon the pivot 3 and is provided with the arm 4, having the aperture 5 by which it may be connected to ope'atively engage mechanism to be actuate The pivot 3 is carried by the sector plate 6, having the apertures 7 by which it may be secured to any stationary part of the mafipedfltoation 01 Letters Batent.

chine to which it may .be applied, and having the sector 8 provided with teeth 9 disposed-in an arc whose axis is common with said pivot 3.

The lever 1 carries the detent; or bolt 10 arranged to engage in the recesses between the teeth 9, being mounted for longitudinal reciprocation in the guide 12 and being connected directly .with the pivoted hand grip 13 by means of the spring leaf or blade 15 forming the connecting link between the detent 10 and hand grip 13 which is mounted to rock upon the pivot 16 carried by the mounting 17 on said lever 1 just below the handle 2.

. AlthoughI have shown the bolt 10 as being connected with the link 15 by the screw 19, it is to be understood that said bolt may be formed in unitary relation therewith and form an integral inseparable part of the hand grip and its spring blade.-

It will be readily seen that by rocking the hand grip 13 and thereby flexing the blade 15 out of its normal alinement as shown by the dot and dash lines in Fig. 2, the recti- Jineal distance between the bolt 10 and the pivot 16 will be decreased and said bolt withdrawn 9 of the sector 8, and that the spring blade 15 being held under tension will when released tend to thrust the bolt 10 into one of the spaces between said teeth.

In the form of my invention shown in Figs. 3 and 4, the hand lever 21 is formed of substantially parallel bars connected at their free ends and having the handle 22, said lever being fulcrumed to rock upon the pivot 23 and being provided with the arms 24 preferably extending obliquely and having the aperture 25 by which it may be connected with operable mechanism.

The pivot 23 is carried by the sector plate 26, having the apertures 27 by which it may be secured to a stationary part of the machine, and having the toothed sector 28.

In this form of my invention the detent or bolt 30 is mounted to slide in oppositely disposed slots 32 in the respective bars, forming guides therefor and said bolt 30 is connected with the spring blade 33 of the hand grip 35, which is mounted to rock between the bars of the lever 21 upon the pivot 36, to effect the reciprocation of the bolt 30 into and out of engagement with the notches between the teeth of the sector 28.

It may be here noted that my invention is from engagement with the teethand the spring for normally thrusting said vbolt into operative engagement with the teeth of the sector, may be formed as an integral structure, thus eliminating the usual jointed connections and the separate spring for actuating the bolt.

I do not desire to limit my invention to the precise details of construction and arrangement herein set forth as it is obvious that various modifications may be. made therein without departing from the essential features of my invention as defined in the ap ended claims.

aving thus described my invention, I olaim:

1. A hand lever provided with detent mechanism comprising a pivoted hand grip having integral lugs directly pivoted to said lever, a bolt and a spring link connecting said hand grip and bolt integrally formed.

2. A hand lever pivoted to swing about a toothed sector, and having a detent arranged to engage the teeth of said sector, and a pivoted-hand grip having a flat spring leaf con nected with said detent and having integral lugs by which it is pivoted directly to said detent.

said lever, the flexing of which by the movement of said hand grip effects the release of 3. A hand lever pivoted to swing about a toothed sector and having a guide, a detent bolt mounted to reciprocate in said guide, and a hand grip having integral lugs pivotally mounted on said lever and having a flat spring blade serving as a link connected with said bolt. I

4. In a hand lever, the combination with a toothed sector, of substantially parallel bars spaced apart and pivoted to swing about said sector and having oppositely disposed slots, a bolt mounted to slide in said slots, and a hand grip pivoted between said bars and having a spring blade connected with said bolt-and serving as a link, which when flexed by said hand grip effects the movements of said bolt in said slots.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses. SAMUEL L. ALLEN.
